Myself am a vintage Hagstrom enthusiast, including an 8-string bass and a Swede, but am really impressed with this bass.
Not sure of when it was made, but the pot's date codes read early 67.
This model is a very short scale of 24.5", a bass version of the Californian D-100, being the D-100X having the D shaped resonator
From what I can tell, there are not a lot of these
